Thanks Douglas, your solution works great. In the context of the
Assembly macros I mentioned in an
earlier message I'd add something like this to your code:

    define(`mymacro',
    `Lbump(`counter')counter
            mvi     a, $1')

    mymacro(`3')

But the output is not what I'd expect:

    0
    1
    2
    [blank lines]
    Lbump(counter)2:
            mvi     a, 3

Instead I need:

    L2:
            mvi     a, 3
